Change the configuration and affects of it on the Openfire

Hello,
By default, the Openfire select the name of system when configure it. For example, if the name of system is “openfire” and the name of domain is “jason.long” then the address of panel is “openfire.jason.long:9090” . I disjoined the system and wants to change the “openfire.jason.long” to “openfire.long.net”. How can I do it and can it cause any problem?
Any option for it or I should edit configuration file?

Thank you.

Stop the server, edit the conf/openfire.xml file and change true to false

When you restart, you’ll be prompted for the setup again. Simply change the appropriate details.
